In this example, the elements of the set are Unicode checkmarks that are separated by dashes. Manage Settings [CDATA[ One-to-one cardinality. An important special case is when the index set is Cartesian product is the product of any two sets, but this product is actually ordered i.e, the resultant set contains all possible and ordered pairs such that the first element of the pair belongs to the first set and the second element belongs to the second set.Since their order of appearance is important, we call them first and second elements, respectively. Therefore, the existence of the Cartesian product of any two sets in ZFC follows from the axioms of pairing, union, power set, and specification. Create a set with infinitely many elements.
